Rebellyous Foods brings continuous plant-based meat manufacturing to commercial scale with Mock 3 launch

Rebellyous Foods commercially launched its proprietary Mock 3 production system in Washington State at the end of December 2025, marking a milestone in the company’s efforts to reduce the cost and complexity of plant-based meat manufacturing.

The Seattle-based company announced that the system reached full commercial operation on 29-30 December 29, following several years of development. According to Rebellyous, Mock 3 converted conventional batch-based plant-based meat production into a fully continuous, automated, just-in-time process, significantly reducing labor requirements while supporting high-volume output.

Christie Lagally Bradburn, Founder & CEO, said the launch demonstrated that continuous, automated plant-based meat production was now commercially viable at scale.

“It was a momentous final week of 2025 to see that plant-based meat can be made fully continuously, automated in high volumes and with considerably reduced labor compared to conventional methods commercially,” Lagally Bradburn said.

Rebellyous positioned Mock 3 as the latest step in a multi-year manufacturing technology roadmap rather than a standalone development. In September 2024, the company introduced its Mock 2 continuous production system, designed to replace traditional batch processing with a fully automated, high-throughput line. That was followed in January 2025 by a US$2.4 million funding extension to scale Mock 2, which demonstrated production rates of between 2,500 and 5,000 lbs per hour using integrated hydration, emulsification, temperature control, and automated recipe management.

Those earlier deployments laid the technical and operational groundwork for Mock 3, which Rebellyous said now represented its first fully commercial, continuous production system.

The company said Mock 3 was designed to address one of the sector’s most persistent challenges: achieving production cost parity with conventional meat. Cruz Philippe, mechanical design engineer at Rebellyous, said targeted investment in manufacturing technology had been central to reaching that goal.

“Production cost parity is not just about scale. Targeted manufacturing technology development is key to providing cost-parity alt-protein products,” Philippe said. “That is what we’ve delivered with Mock 3 at the end of 2025.”

Philippe added that the system sustained steady-state operation across multiple shifts and allowed output to be scaled up or down in real time to support downstream processing rates.

Rebellyous traced the origins of its continuous manufacturing approach back to its founding in 2017 as Seattle Food Tech. The company was established with the aim of producing plant-based meat more quickly and affordably through automation and novel manufacturing methods. Rebellyous said Mock 3 was capable of reaching production rates of more than 5,000 pounds per hour, placing it in direct competition with high-volume conventional processed chicken production.

The company said the Mock 3 system was protected by 14 US and international patents, with an additional six patents pending.

Lagally Bradburn said reaching commercialization had proven at least as challenging as developing the underlying technology.

“Crossing this commercialization finish line was as challenging, if not more challenging, than developing the technology itself,” she said. “But real-world application of this technology means full realization of the investment in time and money we’ve put into achieving cost-parity alt-meat production.”

The launch followed what Rebellyous described as a strong commercial year in 2025. The company reported 30% sales growth, improved margins, and expansion into 45 of the 50 US states. Its current portfolio comprised seven SKUs, all of which qualified for the USDA National School Lunch Program.

Chief Business Officer Tina Meredith said the company’s focus on institutional foodservice had shaped its manufacturing strategy from the outset.

“We are truly democratizing access to plant-based meat replacements,” Meredith said. “No longer is alt-meat only available to those who can afford premium products. The Mock 3 production system enables price parity for the most cost-sensitive market: the USDA National School Lunch Program.”

Rebellyous primarily served schools, hospitals, and other foodservice customers rather than premium retail channels. The company positioned its manufacturing-led approach as a way to expand access to plant-based options without relying on price premiums.

Founded by former Boeing engineer Lagally Bradburn, Rebellyous said it continued to prioritize automation, throughput, and operational efficiency as it scaled its business. With Mock 3 now operating commercially, the company said it was focused on applying the system to meet growing demand while maintaining margins in price-sensitive markets.

The commercialization of Mock 3 came as plant-based meat producers faced increasing scrutiny over costs, volumes, and long-term viability. Rebellyous said its approach demonstrated that targeted investment in manufacturing technology could deliver competitive economics alongside expanded access to plant-based products.
